Texas Instruments LM258ADR

Overview

LM258ADR from Texas Instruments is a dual operational amplifier optimized for industrial and consumer applications requiring rail-to-rail input capability, low quiescent current (350 µA per amplifier), and operation from 3 V to 32 V supply. It delivers 0.7 MHz unity-gain bandwidth, 0.3 V/µs slew rate, and 7 mV max input offset voltage at 25°C, enabling use in precision sensor signal conditioning and power supply feedback loops.

For engineers reviewing the LM258ADR datasheet, LM258ADR pinout, LM258ADR application, or LM258ADR equivalent, this page provides verified specifications, SOIC-8 package details, functional context for single-supply operation, and validated alternative options for cost-sensitive analog signal chain designs.

Technical Context

The LM258ADR implements two independent high-voltage op amps with common-mode input range extending to ground-critical for direct sensing of low-side current shunts and battery monitoring. Its internal architecture supports stable unity-gain operation without external compensation.

It operates across –25°C to +85°C ambient temperature, features 32 V maximum supply rating, and exhibits 65–80 dB common-mode rejection ratio (CMRR) and 65–100 dB power supply rejection ratio (PSRR), making it suitable for noisy industrial environments where supply ripple and ground bounce must be rejected.

Key Specifications

Pinout & Package

LM258ADR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and gull-wing leads for surface-mount reflow assembly.

FAQ

What is the maximum supply voltage for LM258ADR?

The LM258ADR supports a maximum supply voltage of 32 V across its V+ and V– pins, as specified in the Absolute Maximum Ratings table. This allows safe operation in 24 V industrial systems and legacy 28 V avionics test equipment. Exceeding 32 V risks permanent damage, even briefly. The LM258ADR maintains functionality down to 3 V, supporting battery-powered designs with diminishing cell voltage.

Does LM258ADR have rail-to-rail output capability?

No, the LM258ADR does not provide rail-to-rail output swing. Its output can typically swing within 1.5 V of the positive supply (V+) and as close as 5–20 mV above the negative supply (V–) under light load conditions. For example, with V+ = 5 V and V– = 0 V, the output ranges from ~20 mV to ~3.5 V. This limitation is inherent to its bipolar input/output stage and must be accounted for in single-supply gain calculations.

Can LM258ADR replace LM358DR in existing designs?

Yes, LM258ADR is a direct functional and pin-compatible replacement for LM358DR in most applications. Both share identical SOIC-8 packaging, pinout, and core specifications (7 mV VOS max, 0.7 MHz GBW, 350 µA IQ). The key distinction is LM258ADR's extended temperature range (–25°C to +85°C vs 0°C to +70°C), making it suitable for wider environmental deployment without layout changes.

What is the input bias current specification for LM258ADR?

The LM258ADR exhibits an input bias current of –20 nA to –250 nA at 25°C, with worst-case values reaching –500 nA over its full operating temperature range. This bipolar-input characteristic necessitates matched source impedances on IN+ and IN– pins to minimize offset voltage error. For high-impedance sensor interfaces, this bias current may require guard traces or active cancellation techniques.

Is LM258ADR suitable for single-supply operation?

Yes, LM258ADR is explicitly designed for single-supply operation. Its common-mode input voltage range includes the negative supply rail (V–), allowing direct connection to ground-referenced signals like shunt resistors or thermistors. When powered from 5 V (V+ = 5 V, V– = 0 V), both inputs accept voltages from 0 V to 3.5 V, and the output swings from ~20 mV to ~3.5 V-enabling full functionality without dual supplies.
